Amp recommendations to drive Martin Logan Prodigy?


I need some input here please. I want to upgrade my Bel Canto 200.2 Evo amps. They are great amps but with the system I have right now: Audiomeca Mephisto II cdp, Wytech tube pre-amp and the ML Prodigy, they seem to have become the weak link.
I am a fan of Atmasphere amps, but since my speakers are low impedance 4 Ohm, this is not the amp to go for. (If I had the funds I would upgrade to the top Soundlab electrostats, which are 8 Ohm. They would be a perfect match for the Atmasphere amps. Well, maybe one day)
But back to my original question: I would love some monoblocks with my power hungry ML Prodigy, so one amp I looked at is the Electrocompaniet Nemo. The Mark Levinson 33 is a nice amps also, but above my budget.
Any other amp ideas to get the most out of my speakers?

We have achieved the best results using Spectral amplifiers. They have the fastest response of any amp and the fastest settling time. The result is a larger sound stage and far greater clarity than conventional solid state amps. Krells, Mac's etc. are powerful but to slow for this speaker. The Levinson amp is a good one but on the dark side for this speaker. The M-L team heard our set up and said it was the best they had ever heard. Of course to achieve the best results the entire system must be examined. The larger Classe Audio amps have also given very good results. We would suggest that you stay away from tubes in this case. Hope this helps.
why stay away from tubes i ask? do you sell any tubes? if so do you really think that the spectral sounds more like you are their than tubes?
I just picked up the Prodigy's (1-8-02).....so they are still breakin' in.... The amp I'm using is Pass Labs X350.

My dealer was demo'ing the Prodigy's with the smaller Pass Labs X150.....and this system sound devine: detailed, dynamic and a soundstage that extended well beyond the walls of the listening room.

ML states that the Prodigy's do indeed take some time (100hrs) to reach optimal sound quality......can't wait to get there... :)

Here's some pics of My System
I also use a Pass X350 with my Prodigies and it is a match made in heaven- could not be happier.
A friend of mine runs VTL 750s into his Prodigy's to good effect, although a bad tube has taken them out of commission for the time being before he could give me a final verdict on the combination (they worked very well with his Monolith 3's prior to that). I would also consider the Innersound amp for audition with these or any stats. You might also, if you really like the Atmaspheres, consider trying them with this speaker using the Zero impedance matching transformer--contact vtvu of this forum, he knows quite a bit about this product and I have heard it work quite well with other types of lowish impedance speakers and the Trancendent OTL.
